CHARLES ,E. SAYRE, OF ROCKFORD, ILLINOIS.

MIXER FOR GAS-MACHINES.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed January 26. 1906. Serial No. 298,056.

T all whom it may concern:

Be it known that I, CHARLES E. SAYRE, a citizen of the United States,residing at Rockford, in the county of I/Vinnebago and State ofIllinois, have invented certain new and useful Improvements in Mixersfor Gas- Machines, of which the following is a speci fication.

The object of this invention is to regulate the quality of gas formed bythe mixture of gasolene vapor and air, and-to produce a'uniform mixture.

In the accompanying drawings. Figure 1 is a vertical section of anapparatus containing my improvements. Fig. 2 is a horizontal section ofthe mixing chamber. Fig. 3 is an elevation of the mixing chamber. Fig. 4is a plan view of the support for walking beam. Fig. 5 is a section ofone end of the walking beam. Fig. 6 is a vertical section of the airintake valve.

The gas holder comprises the main chamber 1 and a side extension 2. Thebottom 3 of the main chamber has an opening in which is located a pipe4, and an outlet opening 5 is located in the top 6 of the main chamber.The division wall 7 separates the main chamber from the side extensionand has a horizontal plate 8, 'to the upper face of which is connected asupport 9 by screws 10 passing through the slots 11 into the plate. Fromthe support extend two cars 12 each sup porting a screw 13. A walkingbeam 14 is pivotally supported by the screws 13, which are located aboutmidway of the length of the beam.

.I/Vithin the main chamber 1 is located a hermetically sealed can 15,and which is suspended from the walking beam 14. Within the sideextension 2 is located a weight 16 which has a slidable connection withthe walking beam..

To the bottom of the main chamber is secured the mixing chamber,comprising a series of concentric rings 17, in this instance four innumber, and forming the four spaces 18, 19, 20 and 21, which are curved.Each of the rings is formed with a series of openings 22 which arecovered by a fine wire gauze or screen 23. The openings 22 of one ringare located midway between the open ings of the next ring, in order thata division path may be formed from the center space 18 to the spaceoutside of the outer ring.

Adjacent to the mixing chamber is located an air intake valve shown indetail at Fig. 6. The casing 24 of the air intake valve is connected tothe bottom 3 of the main chamber and has a valve seat 25. ing 26 and adischarge pipe 27 are connected with the casing containing the intakevalve. The discharge pipe 27 extends through the rings 17 of the mixingchamber and terminates within the center space 18.

The valve proper has an enlarged portion 28. A fluted lower section 29of the valve proper and a cylindrical stud 30 extends from the uppersurface of the enlarged portion. A cylindrical cap 31 is located overthe cylindrical stud 30 and is connected therewith by a pin 32 in amanner to permit the cap to wabble as if united thereto by a universaloint. Within the cap 31 is located a ball 33 to which is connected awire 34. The wire extends upward through an opening in the cap.

The end of the walking beam 14 extending beyond the can 15 is fittedwith a semi-spherical socket 35 within which is located a ball 36. Thewire 34 has its upper end connected with the ball 36 thereby forming aconnection between the walking beam and the air intake valve.

Air under pressure is conveyed by the pipe 37 to the casing containingthe air intake valve, and vapor from gasolene is conveyed by the pipe 4to the center space 18 of the mixing chamber. By means of the weight 16slidable on the walking beam the weight of the can and air intake valveare properly balanced. The gasolene vapor entering the center space ofthe mixing chamber will circulate through the various spaces and finallyescape into the mixing chamber, when the gasolene vapor becomes heavyenough it will cause the can to rise, thereby allowing the weight toraise the air intake valve which will allow air to enter the centerspace. 18 and mix with the vapor, thereby reducing its density to theproper richness for illuminating purposes. As the density of the mixturedecreases below the proper point the can will descend, thereby closingthe air intake valve, which will permit more vapor to enter the mixingchamber. The air intake valve is constantly opening and closing, or itmay remain open to an extent to produce the proper mixture of air andvapor.

By means of the slots 11, the walking beam can be moved bodily in itslengthwise An air inlet opendirection to properly place the ball 36 overthe air intake valve.

I claim as my invention.

1. The combination of a gas holder, a mixing chamber located within theholder and comprising a series of concentrically located chambers, thewalls of the chambers formed with openings, and gas and air inletscommunicating with the center chamber.

2. The combination of a gas holder, a mixing chamber located within theholder and comprising a series of concentrically located chambers, thewalls of the chambers formed With screened openings, and gas and airinlets communicating with the center cham- 3. The combination of a gasholder, a mixing chamber located within the holder and comprising aseries of concentrically located chambers, the walls of the chambersformed with openings, the openings being located out of register withone another, and gas and air inlets communicating with the centerchamber.
